Who is Caroline Wozniacki? Tennis Player Claims Family Received Death Threats During Miami Open

The world's No. 2 tennis player, Caroline Wozniacki, claims fans verbally attacked her and her family after she lost to Monica Puig Friday at the Miami Open.

Wozniacki, the Australian Open champion, lost to unseeded Puerto Rican star Monica Puig, with a score of 0-6 6-4 6-4. A lot of fans in the crowd were not too happy about the loss, Wozniacki said.

The 27-year-old tennis star, who is from Denmark, said her parents received death threats from the unfriendly crowd, and that her fiancé's nieces and nephews were cursed at.

"During the match last night people threatened my family, wished death upon my mom and dad, called me names that I can't repeat here and told my fiancé's niece and nephew (who are 10 years old) to sit down and shut the f*ck up, meanwhile security and staff did nothing to prevent this and even accepted this to take place," Wozniacki wrote on Twitter.

She continued in her Twitter post that she wants her fans to cheer for her in the stands, but did not appreciate the crowd's attitude.

"I hope the Miami Open chooses to take this seriously because this is a horrible example to set for the next generation of tennis players and fans,' Wozniacki wrote. "I wish Monica all the best for the rest of the tournament."

Wozniacki's fiancé, retired NBA player David Lee, confirmed the crowd's behavior, and also hoped something will be done to solve this problem.

"Disgusting atmosphere, hope something can be done to prevent this from happening again!" Lee wrote on Twitter.

Miami Open tournament director James Blake released a statement on Saturday, saying that staff and security during the tournament did not see nor were informed about any threats made to the players or to their family members.

"During the match, we had tournament and WTA staff as well as tournament security courtside. They never witnessed, nor were notified, of any specific threats made to the players or their families," Blake said in a statement, which was posted to Twitter by New York Times Sports reporter David Waldstein. "If we had been notified, the situation would have been handled immediately."

Blake, who played tennis for 14 years, won 10 ATP singles titles and was ranked as No. 4 in his career, was appointed as tournament director in January.

"I am grateful for the opportunity to lead the Miami Open team that has been putting on one of the best tennis events for more than 30 years," Blake told the Sun-Sentinel back in January. "As a player, I always loved playing in Miami and I am excited for the opportunity to take the tournament experience to a higher level for the players, sponsors and fans."
